DISADVANTAGES
-
Overhead of cell header (5 bytes per cell)
- Complex mechanisms are used to achieve QoS.
- Congestion may cause cell losses.
- ATM switch is very expensive compared to LAN hardware.
- ATM NIC is more expensive compared to ethernet NIC.
- As ATM is connection-oriented technology, the time required for connection setup and tear down is larger compared to time required to use it
